- The 223-9 sequence is a normal-mode attempt to configure SCSI devices. For
- each SCSI I/O controller card installed in your machine, you can have, at most,
- seven (7) SCSI'ed devices. Each device on a given card must have a unique id
- (address), 0 - 6. The address 7 cannot be used. Why? I dunno, but that's it.
- To solve your problem, just turn the little red (or blue) dial on the back of
- the new drive to a number not already used. It sounds like you are already
- aware of that, though, since you said the addresses conflicted. Don't worry
- about data integrity while changing the device's SCSI address. Heck, I've even
- attached tape and disk drives while the machine is on, commanded cfgmgr, and
- voila!, more DASD! ;-)
